Navigation and Ancillary Information Facility NIF Preparing for Programming Using the SPICE Toolkit January 2008

Navigation and Ancillary Information Facility NIF Preparing for Programming 2 Setting Path to Toolkit Executables Unix –csh, tcsh: Use the set command to add the location of toolkit executables to your path. »set path = ($path /my_directory/toolkit/exe) »set path = ($path /my_directory/cspice/exe) »set path = ($path /my_directory/icy/exe) »set path = ($path /my_directory/mice/exe) –bash »PATH=$PATH:/my_directory/toolkit/exe »PATH=$PATH:/my_directory/cspice/exe »PATH=$PATH:/my_directory/icy/exe »PATH=$PATH:/my_directory/mice/exe Windows –Add location of toolkit executables to the environment variable PATH from the Advanced pane on the System Control Panel (Control Panel->System->Advanced). »drive:\my_directory\toolkit\exe »drive:\my_directory\cspice\exe »drive:\my_directory\icy\exe »drive:\my_directory\mice\exe Replace the italics with the path in which you installed the toolkit on your computer. Recommended for all languages

Navigation and Ancillary Information Facility NIF Preparing for Programming 3 Compile and link an application, say program, against the SPICELIB/CSPICE libraries –Assume SPICE is installed at /naif/toolkit/ or CSPICE is installed at /naif/cspice/ »C $ gcc program.c -I/naif/cspice/include /naif/cspice/lib/csupport.a \ /naif/cspice/lib/cspice.a -lm »FORTRAN $ g77 program.f /naif/toolkit/support.a /naif/toolkit/spicelib.a »Some FORTRAN compilers (e.g. Absoft) require an additional flag " -lU77 " when linking against SPICELIB to pull in the standard Unix symbols The default SPICE library names do not conform to the UNIX convention libname.a. So you cannot use the library path/name options -L/path_to_libs/ and -lname unless you rename the SPICE library. Unix/Linux: Build

Navigation and Ancillary Information Facility NIF Preparing for Programming 4 The standard installation of Microsoft Visual Studio or Visual Toolkit may not update environment variables needed to use the C compiler (cl) from the standard DOS shell. –Environment variables for "cl" - Visual Studio 7: »INCLUDE C:\Program Files\Microsoft Visual Studio.NET\Vc7\include\ C:\Program Files\Microsoft Visual Studio.NET\FrameworkSDK\include\ »LIB C:\Program Files\Microsoft Visual Studio.NET\Vc7\lib\ C:\Program Files\Microsoft Visual Studio.NET\FrameworkSDK\Lib\ »PATH C:\Program Files\Microsoft Visual Studio.NET\Vc7\bin\ Windows: Compiler settings

Navigation and Ancillary Information Facility NIF Preparing for Programming 5 Assume SPICE is installed at C:\naif\toolkit\ with CSPICE installed at C:\naif\cspice\ –Compile and link an application, say program, against the SPICELIB/CSPICE libraries »C > cl program.c -IC:\naif\cspice\include C:\naif\cspice\lib\csupport.lib \ C:\naif\cspice\lib\cspice.lib »FORTRAN > df program.f C:\naif\toolkit\lib\SUPPORT.LIB \ C:\naif\toolkit\lib\SPICELIB.LIB Windows: Builds

Navigation and Ancillary Information Facility NIF Preparing for Programming 6 Icy: Register the Icy DLM to IDL Unix: do one of the following three things 1.Start the IDL application from a shell in the directory containing both icy.dlm and icy.so 2.Set the IDL_DLM_PATH environment variable to include the directory containing icy.dlm and icy.so: »setenv IDL_DLM_PATH 3.Use the IDL register command »IDL> dlm_register, Windows: do one of the following two things 1.Set environment variable IDL_DLM_PATH from the Advanced pane of the System Control panel 2.Use the IDL register command: »IDL> dlm_register, Confirm the IDL registration using the help command IDL> help, ‘icy’, /DLM **ICY - IDL/CSPICE interface from JPL/NAIF (not loaded) Required for “Icy”

Navigation and Ancillary Information Facility NIF Preparing for Programming 7 Use the IDL IDE’s preferences panel to set the current working directory to the location where you will be developing your lessons’ code. Optional: Place your dlm_register command in a start up script. Specify the script using the IDL IDE’s preferences panel. Icy: Using the IDL IDE Recommended for “Icy”

Navigation and Ancillary Information Facility NIF Preparing for Programming 8 Assume Mice is installed at C:\naif\mice\ on Windows, or /naif/mice/ on Unix/Linux. Use of Mice from MATLAB requires the Mice source and library directories exist in the MATLAB search path. –On Windows: »addpath('C:\naif\mice\lib') »addpath('C:\naif\mice\src\mice') –On Unix/Linux: »addpath('/naif/mice/lib') »addpath('/naif/mice/src/mice') Mice Required for “Mice”
